IMPROVEMENT IN CAR-HEATERS.

Specification forming part of Letters Patent No. 191,056, dated May 22, 1877; application filed March 24, 1877.

To all whom it may concern:

Be it known that 1-, EDGAR O. HUNTING- TON, of Saginaw City, in the county of Saginaw and State of Michigan, have invented a new and Improved Car Heater, of which the following is a specification In the accompanying drawing, Figure 1 represents a vertical longitudinal section of my improved car-heater; Fig. 2, a top view with parts cutout; and Fig. 3, a vertical transverse section of the same in line mm, Fig. 1.

Similar letters of reference indicate corresponding parts.

The invention relates to that class of carheaters which are suspended below the bedframe of the car and charged from the outside of the same; and the invention consists of a stove or furnace surrounded by a casing or jacket, to which air is supplied through side registers, to be heated up and transmitted, through drums with registers, to the interior of the car.

In the drawing, A represents a common furnace, which is suspended at the bottom of the car and charged with fuel from the outside, the door being locked in such a manner as to close without danger of opening in case of accidents.

The furnace A is provided with a draftregister below the door, in the usual manner, and with an ash-pit below the grate.

The gases of combustion are conducted through a pipe, A, backward and upward through the car and out at the top of the some. The furnace A is surrounded by a casing or jacket, B, of suitable metal, that forms an airspace around the furnace and receives the air through side registers a.

The jacket B extends by an encircling pipe, B, around the smoke-conducting pipe A, so as to utilize the heat of the smoke in its outward passage, the pipe B having suitable airinlet holes b, that keep up the regular supply of air.

The air is heated up in the casing B and pipe B, and conducted to the interior of the car by drums O, which pass through bottom apertures of the car, and have registers at the upper ends to regulate the discharge of air. One drum, O, is arranged above the furnace below the seat, the other at the opposite side of the car at the end of pipe B.

The drum 0, that is arranged around the stove-pipe A, is provided with a perforated distributing-cylinder, D, that is seated on the drum, and serves also as a guard to the stovepipe. The cars may, by this arrangement, be heated in convenient manner from the outside, without requiring the carrying of fuel and charging of the stove from the inside.

The heat may be regulated as required by turning the registers of the drums, a continuous supply of fresh heated air being provided thereby.

Having thus described my invention, I claim as new and desire to secure by Letters Patent- The case B, with apertures a, and the pipe B, with apertures I), each provided with a drum, 0, in com bination with a car-furnace, A, having pipe A, as and for the purpose specitied.
